I'm embarrased to...
I'm embarrassed to have oncoming drivers see me put on my headlights.
Today it's not such an issue with automatic headlights and daytime running lights but in the days of manual headlight switches when headlights need to be lit I always waited until there was no oncoming traffic if possible. I've had driving lights on some of my newer cars and think the same thing. I don't want oncoming drivers witnessing the illumination.
Who cares what some random oncoming driver thinks? I do. IIN?
